percent means parts out of 100
4%=4/100=0.4/10=0.04/1=0.04
4% of sale=0.04 times sales
so we have
at least means >
so
earnings>2200
earnings=1900+comission on sales
commision on sales=0.04 times sales
2200<1900+0.04timessales
solve for sales

2200<1900+0.04 times sales
subtract 1900 from both sides
300<0.04 times sales
divide both sides by 0.04
7500<sales

he has to sell at least $7500 per month
